An angle bisector divides an angle into equal halves.

The bisection that follows the correct steps is Example 1

From the attached figure, we have:

Example 1

$\angle ABD = \angle DBC$

Example 2

$\angle ABD \ne \angle DBC$

When an angle is bisected, the resulting angles will be equal.

This means that the bisection in example 1 is correct, because angles ABD and DBC are congruent.

While the bisection in example 2 is incorrect, because angles ABD and DBC are not congruent.

Hence, the correct bisector is shown in Example 1.

Answer:
U' = (-1,2)
V' = (2,2)
W' = (0,-2)

Explanation:
The given dilation factor is 1/4
This means that each coordinate point is multiplied by 1/4 to get its dilated image.

For point U:
Point U = (-4,8)
x coordinate of U' = 1/4 * x coordinate of U
x coordinate of U' = 1/4 * -4 = -1
y coordinate of U' = 1/4 * y coordinate of U
y coordinate of U' = 1/4 * 8 = 2
This means that: U' = (-1,2)

For point V:
Point V = (8,8)
x coordinate of V' = 1/4 * x coordinate of V
x coordinate of V' = 1/4 * 8 = 2
y coordinate of V' = 1/4 * y coordinate of V
y coordinate of V' = 1/4 * 8 = 2
This means that: V' = (2,2)

For point W:
Point W = (0,-8)
x coordinate of W' = 1/4 * x coordinate of W
x coordinate of W' = 1/4 * 0 = 0
y coordinate of W' = 1/4 * y coordinate of W
y coordinate of W' = 1/4 * -8 = -2
This means that: W' = (0,-2)

Hope this helps :)
